Jeff - hangin' the old striper stick up for the winter, eh?
When I get ambitious I give my good rods a little soak in the tub, then a little scrub with soapy water, rinse and dry. I've heard that furniture polish is what manufacturers use to restore luster, and I have used it without noticing any ill effects. Honestly though, I don't polish them often. I think I've done it once or twice in my life.
Anyway, I suspect turtle wax would be a good choice too - it reduces ultraviolet rays and all that. Never tried it but autowax seems like a great treatment for the graphite.
What's most important to me is the removal of salt residue from the guide assemblies where even the best rods are known to build a little superficial rust between the metal and the wraps / coatings.
I also take the time to remove any sand or particles that may have found their way into the reel seat or any other orifice.
I lightly sanded the cork before and that made it look pretty until the next time I slimed it. Decided that wasn't important.
TO tell the honest to goodness truth, the only time I ever "detailed" rods was when I was trying to sell them!
